thank you

Problem 3: Field and Potential II a) Find the electric field E(r) a distance r from an infinitely long straight wire containing a uniform charge A per unit length by i) integrating over the charge distribution and ii) by applying Gauss's Law. b) Find the electrostatic potential V(r) a distance r from the same wire by i) integrating over the charge distribution and ii) by integrating E(r) you found in part a). c) Let's consider now a finite wire of length 21, centered at the origin. Assuming that the wire lies along the z-axis, find the potential at point (x, 0, z)
